SHEET-METAL FILING. 1 r

Specification of Letters Patent. Patented Mar, 14, 1916.

. Application filed August 22, 1914. Serial lt'o. 858,008.

To all whom it may concern:

Be it known that I, Gnonon D. MOULTON, a citizen of the United States,residing at Denison, in the county of Grayson and State of Texas, haveinvented certain new and useful Improvements in Sheet-Metal Piling, ofwhich the following is a specification.

My invention relates to new and useful improvements in sheet metalpiling, and its objects are, first, to provide a sheet metal piling ofthe lock joint type that will be positively proof against leakage at thejoints, and second, to provide a sheet metal piling that will notrequire the production of a strong frictional engagement betweenadjacent piling members, thus making 1t possible to use a lesser forcein driving or withdrawing the piling than is posslble when such strongfrictional engagement is produced.

A still further object of the invent1on 1sto provide a device ofthe'character described, that will be strong, durable, simple andefiicient and comparatively inexpensive to produce, also one in whichthe several parts will not be likely to get out of working order.

l/Vith the above and other objects in view, the invention has relationto certain novel features of construction and use, an example of whichis described in the following specification and illustrated in theaccompanving drawings, wherein:

Figure 1 is a fragmentary view of a wall formed bv my improved sheetmetal piling, said wall being shown formed with an angle. Fig. 2 is aplan view of a portion of the wall. Fig. 3 is a perspective view showinga portion of a wall formed by a slightly modified form of piling. Fig. 4is a similar view of another modification. Fig. 5 is a section taken onaa of Fig. 4. Fig. 6 is a section on )b of Fig. 5.

Referring now more particularly to the drawings, wherein like referencecharacters designate similar parts in allthe figures, the numeral 1denotes the sheet metal piling sections, each of which is integrallyformed at its vertical edges with split sleeves as indicated at 2 and 3,the former being somewhat smaller in diameter than the latter. Thesleeve 2 of each section 1 is adapted to fit snugly within the largersleeve 3 of the adjacent section as is shown clearly 1n Figs. 1 and 2.Furthermore, a vertically elongated pointed tongue 1, which is formedintegral with each section 1 and projects diametrically across thesleeve 3 thereof is adapted to project through the opening in the sleeve2 that is introduced within said sleeve 3. The joints are formed asabove described by driving each member 1 down with its sleeve 3embracing the sleeve 2 of another member 1, the two members being in thesame verti cal plane. Previous to being put into use, the opening ofeach sleeve 2 is filled with asphalt or some other bituminous compound,and the same is allowed to harden within the sleeve. When the pilingthus treated is driven as has been already described, the tongues 4;will cut their way into the asphalt 5 contained within the sleeves 2,the contact between the asphalt and said tongues being so positive inits nature that no leakage can possibly occur at the joints.

In the modified construction illustrated in Fig. 3, the sleeves 3 areeach formed in two parts separate from the sections 1, and areoppositely riveted to said sections at the.

pointed edges 4 thereof.

The construction shown in Fig. 4 differs from that shown in Fig. 3 inthat the parts forming the sleeves 3 are provided onlvat the upper andlower extremities of the sheet metal sections, metal.

In each form of my invention, the lower ed es of the sections 1 will besharpened as thus economizing in the indicated at 6 to facilitatedriving, the lower extremities of the sleeves 2 being given cone shapesas lndicated at 7 (see Fig. 6) for the same purpose, and the lower edgesof the sleeves 3 being beveled as indicated at 8 for r the same purpose.

The invention is presented as including all such modifications andchanges as properly come within the scope of the following claims.

What I claim is:

1. A lock joint sheet metal piling comprising sections each having asplit sleeve formed upon one of its vertical edges and having its otherVertical edge formed into a tongue with sharpened edge, the tongue ofeach section passing through and closing the opening in the sleeve of anadjacent section,

in combination with a filling of bituminous material in place in saidsleeve.

2. A look joint sheet metal piling comprising sections each having asplit sleeve formed upon one of its vertical edges and having its othervertical edge formed into a tongue with sharpened edge, the tongue ofeach section passing through and closing In testimony whereof I havesigned my the opening in the sleeve of an adjacent secnameto'thisspecification in the presence of tlon, 1n combination with'a filling ofbltumitwo SLIbSCIIblHg Witnesses.
